Having formed the rim 13 as illustrated in Fig. 3, the next step in the process of forming the container is to apply this rim to the circular cover 14 which is preferably made of wood and which is preferably provided around its upper edge surface with an annular recess 14'. The rim 13 is passed over the cover 14 with the body portion 10 closely engaging the annular edge surface of the cover, until the inwardly directed flange 11 seats upon the surface of the recess 14*, as shown in Fig. 4. The cover is then passed downwardly over the top edge of the vessel 15 which is provided with a plurality of surrounding hoops or bands 16 between the upper and lower edges thereof and also with a band 17 around its extreme lower edge. The outer wall of this vessel is made up of a plurality of staves 18 which are held in assembled relation by the hoops 16 and, in this embodiment. the hoops 16 are made up of circular wire. The uppermost hoop 16 is preferably seated in an annular groove 19 which is formed in the outer surfaces of the staves adjacent their upper ends. The lower wall of this groove is preferably downwardly inclined as shown at 19, leaving an annular space beneath the lower edge of the uppermost hoop 16. When the cover 14 is placed in position on the upper ends of the staves as shown in Fig. 5, the rim 13 extends downwardly over the upper ends of the staves with the lower corrugated portion 10 projecting beyond the upper hoop 16. This corrugated portion 10 is then bent inwardly to form an annular transverse flange 20 which underlies the hoop 16 and thus holds the cover securely in position on the vessel. The transverse corrugations 10 permit this inward bending of the lower edge of the rim without distorting the metal, since the necessary contraction is taken up in the adjustment of the corrugations to the decreased diameter of the inner edge of the flange 20.

In Fig. '7 of the drawings there is illustrated a modified form of the invention in which the container is made up of a plurality of upwardly flaring staves which are held in assembled relation, adjacent their upper ends, by a surrounding hoop '26 made of sheet metal and adapted to coact with an inwardly formed annular groove 25" which is formed in the wall of the container. This metal hoop has an annular outwardly projecting bead 26 along the lower edge thereof and at a point just above its middle part it is provided with an annular inwardly extending bead or pro- Jection or corrugation 20 which seats in the annular groove 25- formed in the vessel. The upper wall of the corrugation 26 is directed outwardly and inclined upwardly to a slight extent to unite with the outwardly directed corrugation or projection 26 which extends around the hoop and unites with the upper edge portion 26 of the hoop which lies in contact with the outer surfaces of the staves which form the container. The inwardly extending corrugation or projection 26 holds the hoop 26 in a predetermined position on the container and the part of the hoop which extends outwardly from the corrugation 26 to the corrugation 26 forms an annular shoulder 26: adapted to coact with the part of the rim which extends around the cover.

In the construction shown in Fig. 'l, the cover 2'! is made of wood or other suitable material and lies upon the upper edge surfaces of the staves which form the container 25. This cover is preferably provided with an annular recess 27' around its upper edge surface and this recess is adapted to receive an inwardly extending transversely corrugated flange 28 which is formed upon the metallic rim 28. The central portion 28 of this rim is uncorrugated but it is provided at its lower edge with a transversely corrugated portion 28 normally extending downwardly as shown by dotted lines to permit the rim to be passed downwardly over the projection 26 of the hoop. After the rim has been passed downwardly to this position, the corrugated part 28 is bent inwardly to form a flange 29 which coacts with the shoulder 26 and thus maintains the cover in position on the vessel. By means of this modification, the lower edge of the rim may be bent inwardly to engage a part of a hoop which is formed of sheet metal and which has considerable width. The rim 28 is formed as in the first embodiment of the invention by providing an elongated strip of metal with two series of transverse corrugations along its edges after which the upper series of corrugations are bent transversely to form the flange 28 before the parts are assembled on the container 25.

In Fig. 8 of the drawings there is shown another modification of the invention which permits the application of the rim to a hoop formed of sheet metal. In this form, the container 30 is formed of upwardly flaring staves which are held in assembled relation adjacent their upper extremities by the surrounding metal hoop 31. This hoop is formed of sheetmetal which is bent to form two beads 31 and 31 on its upper and lower edges, respectively. Between these holds, the hoop isprovided with an inwardly extending projection or corrugation 31 which is adapted to snap into engagement with an annular groove 30 formed in the wall of the container when the hoop is driven upwardly over the flaring staves. The engagement of this corrugation 31 with the groove in the container thus holds the hoop in a predetermined position with respect to the upper edge of the container on which the circular cover 32 is adapted to'seat. This cover is provided with an annular recess 32'- around its upper edge and this recess is engaged by an inwardly extending transversely corrugated flange 33 formed on the upper edge of a metallic rim 33. This rim is provided at its lower edge with a transversely corrugated inwardly extending flange 33 which underlies the bead 31"- formed on the upper edge of the hoop for the purpose of holding the rim and cover in fixed positions with respect to the container 30. In forming the rim 33, an elongated metal band is first provided with two series of transverse corrugations along its edges after which the band has its ends united to form an annular rim and the upper series of corriagations are bent inwardly to form the flange 33. The annular rim is then passed downwardly over the cover 32 with the lower corrugated portion extending beyond the upper bead 31". This lower corrugated portion is then bent inwardly to form the lower transverse fiange 33 engaging the under side of the bead 31*.

The subject-matter of the present invention is claimed broadly in applicant's co-pending application Serial No. 538,094, filed May 18, 1931.

Although three forms of the invention have been illustrated and described in connection with the explanation of one example of the improved method, it will be understood that the container may be made in various forms and by various modifications of the improved method coming within the scope of the appended claims.

I claim:

1. A container comprising a vessel having an annular recess therein adjacent its upper edge, an annular hoop having a part'engaging said recess and having an outwardly extending annular bending one of said series of transverse corrugations inwardly to form an upper inwardly extending flange, placing said rim over said cover with said flange overlying said cover, and then.

bending said other series of corrugations inwardly to form a flange underlying said shoulder on said hoop.

3. A container comprising a vessel having an annular recess therein adjacent its upper edge, an annular sheet metal hoop surrounding said vessel and having an inwardly extending annular bead engaging said recess, said hoop being provided further with an outwardly extending annular bead, a cover seated on said vessel, and an annular metallic rim having a part overlying said cover and having the lower annular edge portion thereof transversely corrugated to permit the bending of this portion inwardly beneath said last-named bead.
